微积分在经济中的应用

Application of The Calculus in Economy

本文给出了利用函数的导数如何计算经济问题中的边际值、弹性系数以及利润的最大值;利用二元函数的条件极值讨论消费者效用最大化的均衡条件和既定成本条件下的产量最大化;利用函数的定积分计算总量函数和消费者剩余。

This paper introduces the main application of the calculus in economy.Use functional derivative and differential to calculate the manimal profit,the maximal utility of consumer under definite estimation,and the maximal production under definite cost.Use functional definite integral to calculate surplus of consumer.
